It seems we have another accident involving a drone.
An Envoy Air passenger plane reported striking a drone while departing Chicago’s O’Hare Airport on Sunday, in what is the just most recent incident of uncrewed aerial vehicles (UAV) endangering commercial craft in restricted airspaces around the globe.
“Departure, Envoy 3,961 we just hit something,” a crew member is heard saying. “I believe we hit a drone about 30 seconds ago. We’d like to return to O’Hare.”
New research has found that artificial intelligence (AI) analyzing medical scans can identify the race of patients with an astonishing degree of accuracy, while their human counterparts cannot. With the Food and Drug Administration (FDA) approving more algorithms for medical use, the researchers are concerned that AI could end up perpetuating racial biases. They are especially concerned that they could not figure out precisely how the machine-learning models were able to identify race, even from heavily corrupted and low-resolution images.
In the study, published on pre-print service Arxiv, an international team of doctors investigated how deep learning models can detect race from medical images. Using private and public chest scans and self-reported data on race and ethnicity, they first assessed how accurate the algorithms were, before investigating the mechanism.
“We hypothesized that if the model was able to identify a patient’s race, this would suggest the models had implicitly learned to recognize racial information despite not being directly trained for that task,” the team wrote in their research.
A dangerous vulnerability in Realtek chipsets used in hundreds of thousands of smart devices from at least 65 vendors is currently under attack from a notorious DDoS botnet gang.
The attacks started last week, according to a report from IoT security firm SAM, and began just three days after fellow security firm IoT Inspector published details about the vulnerability on its blog.
Tracked as CVE-2021–35395, the vulnerability is part of four issues IoT Inspector researchers found in the software development kit (SDK) that ships with multiple Realtek chipsets (SoCs).
New information from a study reported in Stem Cells might result in more effective treatments for osteoarthritis and other cartilage diseases, as well as hereditary disorders affecting cartilage development. Their findings might also point to a new way to accelerate stem cell differentiation for bioengineering cartilage, the researchers say.

The Boeing-owned test Stingray, MQ-25 T1, passed fuel to an E-2D airborne early warning and control (AEW&C) receiver aircraft flown by the US Navy’s (USN’s) Air Test and Evaluation Squadron VX-20 during the event the day prior to the announcement.
“During a test flight from MidAmerica St Louis Airport on 18 August, pilots from VX-20 conducted a successful wake survey behind MQ-25 T1 to ensure performance and stability before making contact with T1’s aerial refuelling drogue. The E-2D received fuel from T1’s aerial refuelling store during the flight,” Boeing said.
This first contact for the Stingray unmanned tanker with an Advanced Hawkeye receiver aircraft came nearly three months after the first aerial refuelling test was performed on 4 June with a Boeing F/A-18F Super Hornet receiver. Both the Advanced Hawkeye and Super Hornet flights were conducted at operationally relevant speeds and altitudes, with both receiver aircraft performing manoeuvres in close proximity to the Stingray.
The scientists behind the new device were working within the realm of nano-supercapacitors (nBSC), which are conventional capacitors but scaled down to the sub-millimeter scale. Developing these types of devices is tricky enough, but the researchers sought to make one that could work safely in the human body to power tiny sensors and implants, which requires swapping out problematic materials and corrosive electrolytes for ones that are biocompatible.
These devices are known as biosupercapacitors and the smallest ones developed to date is larger than 3 mm3, but the scientists have made a huge leap forward in terms of how tiny biosupercapacitors can be. The construction starts with a stack of polymeric layers that are sandwiched together with a light-sensitive photo-resist material that acts as the current collector, a separator membrane, and electrodes made from an electrically conductive biocompatible polymer called PEDOT: PSS.

Hot and humid weather, combined with upper-air disturbances, will put Michigan in a thunderstorm pattern over the next week. The interesting part is the thunderstorms won’t come at the likely time of the day.
Normally summer thunderstorms flare up in the heat of the afternoon and early evening, and then diminish overnight. The recent thunderstorm pattern has a bit of a different life cycle. The thunderstorms have been developing overnight, lasting about 12 hours and diminishing to nothing during the morning.
We could have one of these nighttime thunderstorm cycles each night from tonight through next Monday. By late Monday we will finally have a lowering of the humidity, but only for a few days.
